To all whom tmc/,ij concern.'

Be it known that I, Gnonen W. BOWERS, a citizen of the United States, residing at Iannington, in the county Vof Marion and State of West Virginia have invented a new and useful Closet Mold and Process of Molding, of which theffollowing is'a specification. i i

In lorder that the objects of this invention may be understood clearly, it is necessary toi refer briefly to the general'state'of the priorart. The patentrlto S.'\L. "Barnes, 1,109,313, dated September 1,--1914`discloses a means for fashioning a I:water closet bowl by casting. The slip is drawn frointhe bottom of the mold by removing plugs, therebyleaving holes `in the spoon, 'which must be stopped up. The foot of the closetis made separately and not by a1c`asting process. There is no internal core, and, as aconsequence, the inner and outer sur faces `of the bowl are not subjectedfto the absorbent action of the mold. ."Patent No. 1,183,067, issued on the 16th dayiof 1916, to S. C. Hill, discloses'a means whereby a water closet bowl i is'ffashioned by pouring, a double cast being e'ected, that isboth surfaces of the bowl are subjected to the absorbent action of the mold. In this patent, however, laterally removable parts are provided for the 'formationofthe siphon, and these parts, when removed, leave 'holes in the front of the'bowl, vand the holes mustbe closed by a slab,:fash ioned as an article distinct from thebowl, and inserted as a step separate from j the making 'of thev bowl. a' i The aforesaid patents, I believe, give '-a `fair survey. of the prior art,1and,'vsofa'r as I am advised, no one hitherto' has provposed astep inthe makingof .a water closet, which consists vin fashioning a circumferential'ly continuous bowl and a foot simul-A taneously and integrally by pouring ythe slip between an exterior body and an in.- terior core which?` are 'spaced lfrom each other by a distance equal to thethiclmess of the wall of the finished product, theimold being inverted, if desired, to effect/a` draining ofthe surplus slip byl way of the `saine opening through which the slip isintro duced.` The aforesaid features,v` together ywith others hereinafter alluded 1to,"ch'ari acterize this application, denei-ts objects and point out its patentability.

Within the scope of what is claimed, a

j an upstanding potter, exercisingrthe skill of his craft, may depart from the specific disclosure, withoutdeparting in a corresponding degree from thespiritl of the invention' and 60 without placing the utilityof the invention in jeopardy. 1

In the` acco ,panyingu drawings igure lshows inl top plan, a'device constructed Alin=ffaccordance with Athe invention andlcapablel f ofcarrying out the'process hereinafterdescribed; Figure Elisa vertical section taken approximately 4onthe line 2;#2io-f Figure 1;Figure 3 is atop plan,

`wherein the `cap has been removed; Figure fl is fan end elevation; Figure 5 isa transverse-section" taken approximately on the line '5-5of Figure 2; Figure 6 is a top plan ofthewmold in which the`ring is formed; Figure 7 vis asection on 'the line 7;-7' of 75 F igureI 6; vFigure 8 is "asection on the line 8-8 of Figure 6;' Figure 9 is a section showing the'fmold wherein the closure slab i'smade';` Figure 10 is'asection showing the mold wherein' the bottom ofthe bowl and 80 spoon arefas'hioned; and Figure 1l is'a section showing the mold wherein is produced the member which forms part of the outlet.,

`Iieferring-to Figures 12, 3, 4 and 5, 85 there isshown ajmain mold. including a base 1 in the' lform ofa ringprovided with projection 2. On' the upper surface of the base l there `is a continuous upstanding rib3 extended across the pro- 90 jection 2. flnwardly ofthe? rib 3, the Vbase 1l is depressed'to forni an annular seat- 4c. Transverserib's 5, ofinverted `V-shape, are located Aon .the upper"surface of the base 1 and "extend inwardly from thel periphery thereoftotheannular rib 3, the ribs 5 bej ingrotated at' the front'and lat the back ofthe base, The base 1 is supplied with lipstanding 'lugs 6.v

i The'numeral 7 denotes a bowl core, which, 100 forvthei sake rof lightness, `may be cupshaped, the bowl core including a thinned neclI'S. The bowl core '.7 rests on the seat iofthe'basel within the annular upstanding rib 3, the core 7 having-'in its lower 105 edge a-vnotch 9' (Figure `5) receiving the projection 2` of the base l. Noting Figure 2,itwill be observed that the neck 8 of the bowl core 7 is supplied with an upper surface 10 disposedparallel tothebase 1 the 11o neck having a downwardly inclined surface l1 defining anangle with the surface 10..

The upper end of the neck 8 is provided with a continuous marginal rib' 12 bounding the surfaces 10 and 11. y

A core block 14 is mounted on the surface y10 of the neck 8 and is provided withla cavity 15 wherein a handle 16. is located, to the end that the block may be manipulated conveniently. A core block 17 rests on the have projecting portions 21 received within the marginal rib 12, so las to hold the core blocks in position against sliding movement.

A pair of side members 22 is provided, the

` side members beingsupported on the base 1.

`lhe'side members 22 have notches 23; which receive thenlugs 6 on the base 1. The inner surfaces of the side members 22 abutI against the outer surface of the rib 3 on .the base 1, as shown `in Figure 5, the inner surfaces of the side members-being` separated from the outer surfaces of the bowl core 7 ,the 4neck 8 thereof, andy the blocks 14 and 1,7, sothat ar space 24'eXists, into lwhich the slip may be poured. -The side members 22 have ver` tical abutting edges provided withV interengaged lugs and recesses which prevent relative movement between the side members.

, Theside members 22 are beveled at the lower ends of their abutting edges, las shown at'2-6,

to receive the transverse ribs 5 on the base 1. `The members 22 are beveled, as indicated at 27, at the upper ends of their abutting edges, the said members being` cut away, as indicated at 28 in Figure 4, to receive the proj ections 2 on the base 1. In the upper ends -of the members 22 there exists a recess 29.

See Figures2 and 5.

A cap 30 is superposed on the upper ends l of the side members 22 and has a depending projection 31 (Figure 5) extended part way down into the recess 29 of the side members 22,50 that the cap cannot move laterally lwith respect'to the side members. The cap 30 is providediwith a depending V-shaped rib at its front Iand at its back (Figure 4),

' these ribsbeing received between the beveled portions 27 (Figure 3) of the side members `22. There is an opening 33 in the cap 30, through which the slip may be poured into the space 24 above alludedfto.

From the foregoing, it will be obviousthat the device described includes a mold comprising a body and acore in the body, the body and the core being spaced by a distance equal to the thickness of the'wall of the finished product and represented by the space24. Into this space 'the slip is poured, through the hole'33, the bowl and the foot ofthe closet being formed integrally and simul taneously, by casting, the recess 29 providing for the formation of the foot, a double cast being effected, since both surfaces/of the product-are subjected to the absorbent action of the mold. It is to be observed that not only'are the bowl and the'foot formed integrallyand simultaneously by casting, but, as well, the bowl is circumferentially ccntinuous, that is, there are no openings in the circumference of the bowl, which must be lled up with slabs or the like.

The closet is completed in a more or less conventionaland common Way. Thus,'the rim is made in a mold 34v comprising abase 35 and a top 36, Figures 6, 7 and8 being noted. The base and the top have coacting annular grooves`37, .and thereis an'enlargement 38 lin the members 35 kand 36, wherein the inlet member for the rim isifashioned.

Openings 40 are provided zint-he vniember36,

for the receptionofpins (not shown), which form `thefholes for the attachment of the seat. Thelmold is set up edgewise,.and the slip is poured in throughan opening.V defined by cooperating notches 39 in the parts 35 and36. Y Y ,-7

The` spoon ismade, ina mold `shown in Figure 11, the mold comprising a base 141 and a top 42, the tophavinga pouring aperture 43.4 The surplus slip may-bev poured ing parts 49 and 50, themember 50 having a pouring opening 51. Y

I claimzfr, Y

1. In the p-rocessof making a water closet including a bowl anda baser projecting laterally beyond the Vbowl,"steps` which com'- prise. fashioning the bowl of circumferentially continuous form, and fashioning the bowl-andthe base integrally and in. one .uninterrupted operation, by pouring the slip between an absorbent external `mold body andan absorbent` internal mold core, which are spaced from Veach other by :a distance equalto the thickness of the wall of the nished product, the ybase being subjected to the absorbent action of the moldat the point of juncture between the base and the bowl, and beyond the periphery vofthe bowl, the mold being inverted duringthe pouring of the slip, thereby permitting the slip to flow laterally and form'the base, subsequent to the formation ofthe bowl, the mold being reversed to permit the surplus slip to drain through the saine opening through vwhich the slip lisintroduced during the casting operation. A

Y 1 2. Awater closet mold comprising an auiet blocks; and e cap supported on the side members and having a pouring opening, the l5 bowl core and the core blocks having interengaging elements serving to hold the core blocks in place on the bowl core.

In testimony that I claim the foregoing as my own, I have hereto affixed my signa- 20 ture in the presence of two witnesses.
